US 5,627,665 A · Liquid crystal display device and method for producing the same

Abstract

According to the present invention, a display medium layer is sandwiched between a TFT substrate and a counter substrate. In the display medium layer, resin walls are respectively formed in regions other than those where a plurality of segmented electrodes are formed, and liquid crystal portions are respectively formed in regions between the respective resin walls, corresponding to those where the segmented electrodes are formed. Disclination lines are formed on the interfaces between the resin walls and the liquid crystal regions. In a liquid crystal display device, liquid crystal molecules in the liquid crystal regions are radially oriented and at least one liquid crystal domain is formed in each liquid crystal region.

Dependent claims

A method for producing a liquid crystal display device comprising the steps of:

(1) providing a mixture containing a liquid crystalline compound and a photopolymerizable compound between two substrates, at least one of which is transparent;
and
(2) irradiating light having a predetermined irradiation intensity distribution to the mixture between the two substrates, allowing a phase separation of the mixture involved in polymerization thereof to be effected, and uniformly distributing supporting walls made of a resin and a liquid crystal.

Dependencies are inferred from the claim text.
